Sound Processing in Smart Home Devices – The System Approach
Speech, as the most natural way we express ourselves, has tremendous potential as a method of human-machine interface. Speech recognition technologies have improved significantly but are still dependent on factors that influence the signal to “noise” ratio. During the last three years Alango, a leading provider of speech and audio enhancement DSP technologies, has accumulated significant practical experience in integration of front-end speech enhancement and speech recognition. In this presentation we will discuss all aspects of signal processing in Smart Home devices, including multi-microphone beamforming, echo cancellation, as well as keyword recognition and the computational resources necessary to perform such tasks. We’ll discuss both technology and system aspects. Additionally, we will share our vision for the voice interface of the future and discuss R&D topics to make it a reality.
Alango Technolohies presents Wear & Hear line
To address the needs of the huge potential market of over 700 million hearing impaired users worldwide, Alango Technologies, Ltd., a leading supplier of voice and audio enhancement technologies for the communication and entertainment markets, launched its “Wear & Hear” line of personalized hearing products. The Wear & Hear line provides an alternative to hearing aids, which are used by less than 10% of those who need hearing assistance worldwide due to a combination of high prices, limited functionality, and associated stigma. Alango’s years of practical experience developing digital sound processing technologies are incorporated into affordable consumer electronics devices that provide customizable hearing enhancement to the wearer. The first Wear & Hear personalized hearing product to reach the market is called BeHear™, a stylish Bluetooth headset. The second product is called Smart Assistive Listening Transceiver (SALT™) that, additionally, integrates assistive listening features.
Product Demo for BeHear at WTS 2017 is scheduled for Tuesday, March 7th at 3:15 pm on the Wearable & Technology Innovation Stage, London.
We recently added a section to our website called “Our Posts”. This is a place for members of Alango to express what is on our mind with regard to the technology we provide to the world. “Our Posts” are typically informal. Sometimes we provide cultural or personal anecdotes with historic undertones that relate in some way to our technology. Other times we discuss important developments in the industry or even key regulatory issues that represent a significant change in the world of voice, hearing, or audio. Alango’s slogan is “DSP Technologies for Life” because the technologies we supply enhance communications enriching the human experience. This is a way of life for us and maybe you too. So please take a look at our posts and feel free to send a comment.
Alango's unique Automatic Volume and eQualization for Music and Entertainment (AVQ-Me™) technology is now availabel for headsets based on BlueCore5 Multimedia. Enjoying music in a mobile environment is often spoiled by strong, dynamically changing ambient noises. Volume and equalizer settings optimal for specific conditions quickly become not optimal or even uncomfortable. Trains, subway, buses are just a few examples of such dynamic environments. AVQ-Me™ technology significantly enhances mobile listener's experience by automatic compensation for changes in the ambient noise level and spectrum. The built-in microphone of a stereo headset is used to monitor the ambient noise conditions and the audio signal is amplified and equalized accordingly. You don't need to touch the sound controls again!
